Phys.org / Tabby's star may be orbited by a planetary-mass companion
By analyzing data from NASA's Transiting Exoplanet Survey Satellite (TESS) and conducting new radial velocity measurements, U.K. and French astronomers have found evidence that the mysterious Tabby's star may be orbited by ...
Medical Xpress / Climate change is redrawing the malaria map in Africa, study finds
Malaria is the deadliest climate-sensitive infectious disease. Yet researchers and public health officials have long argued over how climate change has shaped its spread. A new Nature study resolves this debate, providing ...
Medical Xpress / Chemicals present in drinking water may carry a hidden risk tied to uterine cancer
In a recent study, researchers examined whether certain chemicals present in public drinking water are linked to uterine cancer, the most common gynecological cancer in the United States and one that has been steadily increasing ...
Tech Xplore / OpenAI says rogue AI agent attack hit other companies
ChatGPT-maker OpenAI has revealed that an autonomous artificial intelligence agent that hacked a popular platform for computer programmers also attempted to breach four other companies during the incident.
Phys.org / A successful, sustainable catalyst for ethanol dehydrogenation
Ethanol is an alcohol used in a vast number of industrial and household applications. When dehydrogenated—in this case, stripped of some of its hydrogen atoms—it yields another important compound: acetaldehyde, which is used ...
Phys.org / Private mission to rescue NASA's aging telescope runs into its own trouble
The spacecraft rushing to the rescue of an aging and sinking NASA telescope has run into its own problem.
Phys.org / The cost of memory: How organisms balance thinking and sensing
Remembering the past can help living organisms make better decisions, but memory comes at a cost. Whether it is an animal searching for food or a single cell responding to its surroundings, storing and using information requires ...
Phys.org / Finding order in the inner chaos of our cells: Shape-shifting proteins get a design tool
The vast majority of proteins in our bodies contain regions that are in a constant state of wiggling, shape-shifting every few nanoseconds to completely change how they look. Information on how these shape-shifting proteins ...
Medical Xpress / New mechanism reveals how heart cells resist regenerative reprogramming
Specialized cells in the human body make biological trade-offs to perform certain jobs. To support the large, hardworking hearts that power other organs, heart cells have evolved to be extremely efficient and resilient. Because ...
Phys.org / Moon's thick crust could amplify elusive gravitational-wave signals
Gravitational waves are tiny ripples in the fabric of spacetime that are produced when massive objects in the cosmos accelerate or collide. By detecting these waves, astrophysicists can study various cosmic events, including ...
Tech Xplore / Strike a pose: Creating more realistic multi-person images
Generating an image of a person on a computer using text prompts is easy. Generating one with two people is similarly simple. But creating an image of multiple people actually doing something, and faithfully reproducing not ...
Phys.org / Extragalactic positron-annihilation hotspots might mean Milky Way produces far more positrons than thought
Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a distinctive 511 keV gamma-ray signal. ...
